Description

Technical Field

[0001] This utility model relates to a quick connector, specifically a quick connector for aluminum alloy profiles, which is used for the quick installation and disassembly of aluminum alloy profiles in medium and light-duty equipment, and belongs to the technical field of equipment installation accessories in manufacturing. Background Technology

[0002] Quick couplings are widely used in the installation of manufacturing equipment, featuring quick installation, easy disassembly, and good stability, thus improving the installation efficiency of mechanical equipment. Furthermore, aluminum alloy profiles are widely used in modern manufacturing equipment.

[0003] However, existing aluminum alloy profiles are mostly connected using threaded special accessories during installation. Although the installation is relatively convenient and flexible, there is room for improvement in installation efficiency.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative quick connector for aluminum alloy profiles to improve installation efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an aluminum alloy profile quick connector that has a reasonable structure, reliable performance, stable and safe connection, and convenient assembly and disassembly.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick connector for aluminum alloy profiles, comprising a cylindrical wall, an inner liner, a pressure head, and an elastic lever; wherein, the cylindrical wall is provided with a groove and a limiting surface, the inner liner is installed and fixed on the groove, the limiting surface restricts the end position of the profile and bears the axial load of the profile; the inner liner is installed and fixed on the cylindrical wall, and the inner liner is provided with two bosses and a groove, the lower boss is installed in the groove of the cylindrical wall, and a small gap is provided between the upper boss and the outer end of the cylindrical wall. The elastic lever is installed and fixed on the groove of the inner liner, and when no downward bending deformation occurs, it fixes the axial displacement of the aluminum alloy profile. Under the action of external force, the elastic lever can bend and deform downward along the axial direction of the inner liner. At this time, the axial fixation of the aluminum alloy profile can be released, and it can be quickly reset after the external force is removed. The pressure head is installed on the liner, with its lower end in contact with the elastic lever. Under the action of external force, it can make a small downward displacement along the axial direction of the liner, pressing the elastic lever to move along the axial direction of the liner. After the external force is removed, the pressure head returns to its original position under the elastic action of the elastic lever.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. The quick connector for aluminum alloy profiles of this utility model has stable performance, simple structure, low cost, and is easy to mass-produce.

[0009] 2. The quick connector for aluminum alloy profiles of this utility model allows for easy installation by simply inserting the two profiles directly into the connector; disassembly is also convenient by pressing down the pressure head. Attached Figure Description

[0015] Figure 6 yes Figure 5 Enlarged views of parts I, II, and III. Detailed Implementation

[0016] A quick connector for aluminum alloy profiles is characterized in that: the pressure head has a square hole; when the pressure head is pressed down, the elastic tab bends downward, allowing the profile to be axially installed into the cylinder wall along the square hole. Installation is completed when the lower end face of the profile contacts the cylinder wall limiting surface. The cylinder wall limiting surface restricts the end position of the profile and bears the axial load. Then, the pressure head is released, and the elastic tab returns to its original position. The interference fit between the elastic tab and the profile restricts the axial displacement of the profile. During disassembly, the pressure head is pressed down, forcing the elastic tab to bend downward, thus disengaging the elastic tab from the outer surface of the profile and releasing the axial fixation of the profile by the elastic tab.

[0017] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 6 This utility model is a quick connector made of aluminum alloy profile. It is die-cast from a cylindrical wall 1, an inner liner 2, a pressure head 3, and an elastic lever 4. The overall structure is completely symmetrical along the middle plane of the cylindrical wall 1. Taking the upper half as an example, the structure and principle of the lower half are completely the same as those of the upper half.

[0018] The cylinder wall 1 is provided with a groove 101 and a limiting surface 102. The inner liner 2 is installed and fixed on the groove 101, and the limiting surface 102 restricts the end position of the aluminum alloy profile and bears the axial load of the profile. The inner liner 2 is installed and fixed on the cylinder wall 1, and the pressure head 3 is installed on the inner liner 2. Axial positioning is achieved by the internal boss and elastic lever 4 of the inner liner 2. The inner liner is provided with an upper boss 201, a lower boss 204, an inner boss 202, and a groove 203. The lower boss 204 is installed in the groove 101 of the cylinder wall. The lower surface of the upper boss 201 is parallel to the axial outer end face of the cylinder wall and has a small gap. The shape of the part of the elastic lever that contacts the profile is consistent with the external shape of the profile. The end that contacts the profile has several concave surfaces to increase the contact area with the profile surface. The elastic lever 4 is fixedly mounted on the groove 203 of the inner liner 2. When no deformation occurs, the radial inner end face of the elastic lever 4 is in interference contact with the outer surface of the aluminum alloy profile to fix the axial displacement of the profile. Simultaneously, to improve the reliability of the elastic lever 4 in fixing the profile axially, several grooves are provided on the contact surface between the elastic lever and the aluminum alloy profile to increase the roughness of the contact surface, such as... Figure 6 As shown, this increases friction. The elastic lever 4, under external force, can bend axially downwards along the inner lining 2, forcing the elastic lever 4 to disengage from the outer surface of the profile. At this point, the axial fixation of the aluminum alloy profile can be released. After the external force is removed, the elastic lever 4 can quickly return to its original position. The pressure head 3 is mounted on the inner lining 2, with its lower end contacting the elastic lever 4, and its lower boss 302 contacting the inner boss 202 of the inner lining 2. This forces the pressure head to only make a small axial displacement downwards within the elastic deformation range of the elastic lever 4, without disengaging from the inner lining 2. The pressure head 3 can make a small downward displacement along the axial direction of the inner lining 2 under external force, pressing the elastic lever 4 downwards to bend and deform, releasing the fixation of the profile. After the external force is removed, the elastic lever 4 returns to its original position under its own elasticity, restoring the axial fixation of the profile. The pressure head 3 also returns to its original position simultaneously under the resetting action of the elastic lever 4.

[0019] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
